First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Call a physician or poison control center immediately. If not breathing, give artificial respiration.
Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Keep eye wide open while rinsing.
Drink plenty of water. Never give anything by mouth to an unconscious person.
Symptoms: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation
Immediate Medical Attention
Immediate medical attention is required for all exposure routes. Call a physician or poison control center immediately.
Medical Treatment
Treat symptomatically.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Use only under a chemical fume hood. Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Do not breathe dust. Do not ingest. If swallowed then seek immediate medical assistance.
Keep containers tightly closed in a dry, cool and well-ventilated place. Corrosives area.
Handle in accordance with good industrial hygiene and safety practice.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use only under a chemical fume hood. Ensure that eyewash stations and safety showers are close to the workstation location. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source
Protective gloves. Gloves material: Butyl rubber, Breakthrough time: > 480 minutes, Gloves thickness: 0.7 mm, EU standard: EN 374, Gloves comments: (minimum requirement). Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) Ensure gloves are suitable for the task: Chemical compatibility, Dexterity, Operational conditions, User susceptibility, e.g. sensitisation effects, also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion. Remove gloves with care avoiding skin contamination.
Goggles (European standard - EN 166)
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. To protect the wearer, respiratory protective equipment must be the correct fit and be used and maintained properly. Large scale/emergency use: Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced Recommended Filter type: Particulates filter conforming to EN 143. Small scale/Laboratory use: Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended half mask:- Valve filtering: EN405; or; Half mask: EN140; plus filter, EN 141 When RPE is used a face piece Fit Test should be conducted
